Efekt je prý dlouhodobý. Pokud by to fungovalo, mohlo být zajímavé asi hlavně do skleníku. Zkoušel to někdo z místních profíků?
„However, the technique he favours above all is to remove a complete ring of bark, about half an inch in (1.3cm) width, from the main stem of a young fig tree, and to then replace it upside down and cover in the same way as covering a conventional graft. This works because the vascular tissue of the phloem, found just underneath the bark, which transports the products of photosynthesis (sugar) throughout the plant has polarity. In other words it doesn’t work as efficiently in transporting food to the root system if turned upside down resulting in a sort of modified ring barking effect but without the danger of killing the plant. Apparently the effect is quite long lasting and reduces the vigour of the fig tree markedly, giving the short compact growth which leads to fruit production. In addition Brooke noted that such sturdy growth is also more cold hardy and so less prone to frost damage in winter.“
